# How many p orbitals are there in a neon atom?

##### 1 Answer

Three.

#### Explanation:

Your tool of choice for this problem will be neon's electron configuration.

*Neon*, *neutral* neon atom will have a total of

Now, neon's electron configuration, which must account for

#"Ne: " 1s^2 2s^2 2p^6#

So, a neon atom has

two electronslocated in the1s-orbitaltwo electronslocated in the2s-orbitalsix electronslocated in the2p-orbitals

To get the number of p-orbitals you have, you can use quantum numbers.

The first energy level that can hold p-orbitals is the second energy level, for which the *principal quantum number*,

The principal quantum numbers talls you the energy level, or **shell**. The *angular momentum quantum number*, **subshell**.

In your case, the p-orbitals correspond to an angular momentum quantum number equal to

Now, the **number of orbitals** you get *per subshell* is given by the *magnetic quantum number*,

#m_l = {-1; 0; 1}#

This means that you can find a total of **three** p-orbitals,

In neon's case, since its only p-orbitals are located on the second energy level, it follows that it contains a total of **three** p-orbitals,
